Ellis Department of Terrestrial Zoology, Western Australian Museum, Locked Bag 49, Welshpool DC, Western Australia 6986, Australia. Biologic Environmental Survey, 24–26 Wickham St, East Perth, Western Australia 6004, Australia. Email: [email protected] ABSTRACT – The Western Australian Museum holds a vast collection of specimens representing a large portion of the 106 currently recognised taxa of dragon lizards (family Agamidae) known to occur across Australia. While the museum’s collection is dominated by Western Australian species, it also contains a selection of specimens from localities in other Australian states and a small selection from outside of Australia. Currently the museum’s collection contains 18,914 agamid specimens representing 89 of the 106 currently recognised taxa from across Australia and 27 from outside of Australia. This includes 824 type specimens representing 45 currently recognised taxa and three synonymised taxa, comprising 43 holotypes, three syntypes and 779 paratypes. Of the paratypes, a total of 43 specimens have been gifted to other collections, disposed or could not be located and are considered lost. An annotated catalogue is provided for all agamid type material currently and previously maintained in the herpetological collection of the Western Australian Museum. KEYWORDS: type specimens, holotype, syntype, paratype, dragon lizard, nomenclature. INTRODUCTION Australia was named by John Edward Gray in 1825, The Agamidae, commonly referred to as dragon Clamydosaurus kingii Gray, 1825 [now Chlamydosaurus lizards, comprises over 480 taxa worldwide, occurring kingii (Gray, 1825)].

  • Habitat Types
    Habitat Types The following section features ten predominant habitat types on the West Coast of the Eyre Peninsula, South Australia. It provides a description of each habitat type and the native plant and fauna species that commonly occur there. The fauna species lists in this section are not limited to the species included in this publication and include other coastal fauna species. Fauna species included in this publication are printed in bold. Information is also provided on specific threats and reference sites for each habitat type. The habitat types presented are generally either characteristic of high-energy exposed coastline or low-energy sheltered coastline. Open sandy beaches, non-vegetated dunefields, coastal cliffs and cliff tops are all typically found along high energy, exposed coastline, while mangroves, sand flats and saltmarsh/samphire are characteristic of low energy, sheltered coastline. Habitat Types Coastal Dune Shrublands NATURAL DISTRIBUTION shrublands of larger vegetation occur on more stable dunes and Found throughout the coastal environment, from low beachfront cliff-top dunes with deep stable sand. Most large dune shrublands locations to elevated clifftops, wherever sand can accumulate. will be composed of a mosaic of transitional vegetation patches ranging from bare sand to dense shrub cover. DESCRIPTION This habitat type is associated with sandy coastal dunes occurring The understory generally consists of moderate to high diversity of along exposed and sometimes more sheltered coastline. Dunes are low shrubs, sedges and groundcovers. Understory diversity is often created by the deposition of dry sand particles from the beach by driven by the position and aspect of the dune slope.

ABSTRACT – The Australian pygopodid genus Aprasia comprises a group of small, morphologically conservative, worm-like fossorial lizards, many of which are distributed along the west coast of the continent. This study re-examines the taxonomic distinctiveness of the two most northerly occurring species in Western Australia: A. fusca and A. rostrata, which are very similar in morphology. A combined morphological and allozyme analysis revealed these two species to be conspecifi c with A. rostrata considered a senior synonym of A. fusca. As a consequence, we have redescribed A. rostrata. The allozyme analysis also revealed a new species, named here as Aprasia litorea sp. nov. This species occurs in the Lake Macleod region, well to the south of its congener, A. rostrata, and the two species are diagnosable using a conservative suite of morphological and meristic characters.
